发布时间：2019-08-24 09:57
【摘要】：对六盘水矿区煤矸石原粉组成进行分析,测定了煤矸石原粉和活化煤矸石粉制备免烧砖的胶凝性能,系统地研究了机械、热、化学及复合活化方式对原状煤矸石活性激发作用。研究表明,六盘水矿区煤矸石属于高铁高砂型煤矸石,活化煤矸石能够显著提高煤矸石基免烧砖的胶凝性能,复合活化效果优于单一活化方式,复合活化的煤矸石能够大幅度地提高免烧砖的胶凝性能,达到JC/T422-91(96)《非烧结普通黏土砖》MU15的标准。
[Abstract]:The composition of coal gangue raw powder in Liupanshui mining area was analyzed, and the cementitious properties of unfired brick prepared by coal gangue raw powder and activated coal gangue powder were measured. The activation effect of mechanical, thermal, chemical and compound activation methods on the activity of unburned coal gangue was systematically studied. The results show that the coal gangue in Liupanshui mining area belongs to high speed iron and high sand coal gangue. Activated coal gangue can significantly improve the cementitious performance of coal gangue based unfired brick, and the compound activation effect is better than that of single activation mode. The compound activated coal gangue can greatly improve the cementitious property of unfired brick, which meets the standard of JC/T422-91 (96) "unsintered ordinary clay brick > MU15".
